Premotor, motor and nonmotor symptoms of Parkinson's disease are described in the article below.
1. Motor symptoms
The four main motor symptoms of Parkinson's disease are tremor, muscle stiffness, bradykinesia, and postural instability, as defined by the acronym TRAP (tremor, rigidity, akinesia (or bradykinesia), and postural instability). (Table 1-1). Secondary motor symptoms include decreased swinging of the arms, decreased blink frequency, masked facial expressions (hypomimia), decreased voice volume (hypophonia), and difficulty turning in bed.
Run refers to pulsating rhythmic fluctuations around a fixed point during rest or a non-postural position. Tremor is often the first motor symptom of Parkinson's disease and occurs in about 90% of patients at some point in their lives. While the tremor of Parkinson's disease is typically a resting tremor, 50% of patients may also present with a tremor that may reappear with extension of the arms. The tremor starts out asymmetrically and is characterized by a pronation and back, or ball roll, that eventually affects the opposite side of the body. Tremor may be poorly responsive to pharmacological treatments, including levodopa.
Stiffness refers to stiffness or resistance of a limb when it is passively flexed, activating both agonist and antagonist muscles, and may also be called a cog wheel. Stagnation means slow movement (no movement means no movement) and can occur both during initiation and maintenance of movement.

Postural instability, or balance dysfunction, appears later in the course of the disease, about a decade after the initial diagnosis. Postural instability is correlated with disease severity and is demonstrated by tensile testing. It is a symptom of levodopa resistance, as opposed to bradykinesia, muscle stiffness, and tremor. Postural instability is a major cause of falls, causing hip fractures, loss of independence, and home nursing for patients.

Other terms associated with Parkinson's disease symptoms include dyskinesia, also called levodopa dyskinesia, which refers to abnormal, involuntary, chorea-like movements that can be in the limbs, head, and trunk me. Levodopa-induced dyskinesia may also present with swinging, myoclonus, dystonia, or a combination of these movements. Levodopa-induced dyskinesia may be further classified as peak-dose dyskinesia, time-off or wearing-off dyskinesia, or biphasic dyskinesia. Biphasic dyskinesia begins soon after taking levodopa, followed by improvement in Parkinson's symptoms and dyskinesia and then a return of dyskinesia as dopamine levels decrease.
Dystrophy refers to involuntary, prolonged muscle contractions with abnormal postures, often in the extremities. Dystonicity often occurs with times of low dopamine levels, often during the early morning hours. Patients may twist their toes or invert the foot due to instep or plantar flexion, which can lead to leg cramps or pain. Dystonicity can also occur at peak dose, biphasic, or the “off” state.

Motor oscillation refers to an “off” time, when there is a poor response to levodopa, alternating with an “on” period, i.e. a time of improvement in function. Motor oscillations occur with advanced disease, possibly because of fluctuating stimulation from levodopa on postsynaptic receptors. Off periods are predictable, during which symptoms emerge before the next dose, or can be unpredictable. Dose failure means that levodopa has a slow clinical effect. Freeze is described by Giladi and Nieuwboer as “an episodic inability (lasting a few seconds) followed by effective walking with no known cause other than Parkinson's syndrome or gait disorders. severity level. This is most common while turning and starting to walk but can also be seen when confined to confined spaces, when stressed, and when distracted.” Patients feel that their feet are glued to the ground, and this sensation is often essentially intermittent.
2. Non-motor symptoms
Over the past 20 years, there has been an increasing understanding of the importance of nonmotor symptoms (that is, symptoms other than those associated with movement, such as tremor, muscle stiffness, and bradykinesia) in the diagnosis and treatment of Parkinson's disease. It is estimated that nearly all patients with Parkinson's will have some accompanying nonmotor symptoms throughout the course of the disease. The impact of non-motor symptoms is often greater than that of motor symptoms; but unfortunately, nonmotor symptoms often go undetected. The nonmotor symptoms of Parkinson's disease are listed below and are in Table 1-1.
Neuropsychiatric non-motor symptoms include depression, apathy, apathy, desire control disorder, anxiety, psychosis, hallucinations, emotional disturbances, loss of will. Cognitive non-motor symptoms include executive dysfunction, memory loss, and dementia.

Autonomic disorders including orthostatic hypotension, constipation, urinary incontinence, sexual dysfunction, altered cardiac reflexes, olfactory dysfunction, gastric dysfunction intestines, and sweating. Sleep disturbances including insomnia, somnolence, excessive daytime sleepiness, restless legs syndrome, episodes of sleep, cyclic limb movements during sleep, and ocular movement disturbances fast (REM). Sensory abnormalities include pain, numbness, fatigue, and decreased sense of smell. Non-motor symptoms may also fluctuate. During off periods, patients may experience worsening of emotions, anxiety, autonomic disturbances including sweating and irregular body temperature, pain/numbness, and other symptoms. Non-motor symptoms during the on episodes can include mania, agitation, paranoia, obsessions, and impulsivity.
3. Pre-exercise symptoms
Premotor symptoms are defined as symptoms that precede the motor symptoms of Parkinson's disease and include constipation, loss of sense of smell, REM sleep behavior disturbances, and depression (Table 1). -first ).
